Abstract: Copolymers are produced when a 3,4-epoxy-1-butene monomer is copolymerized with an imidized maleic anhydride (maleimide) monomer in the presence of a free radical initiator. The copolymerization comprises both 1,2-propagation and 1,4-propagation of 3,4-epoxy-1-butene. Alternately, a maleamic acid or maleimide functionality may be introduced into a copolymer containing 3,4-epoxy-1-butene and maleic anhydride by introducing a primary amine into the reaction mixture. The structure and composition of the product copolymer are controlled by both the sequence and conditions of the reaction. Products of this invention can be cast as clear films and can also be used as reactive polymers.

Abstract: A multiple photosensitive element array and lens system particularly adapted for use in a camera (10) for providing scene image light intensity signals for use in automatic exposure and automatic focus control. A two-dimensional photometric sensor array (30) of planar photosensitive array segments is centrally disposed on an integrated circuit substrate so that the planar segments each receive light from corresponding segments of the image focused thereon for developing first light intensity related signals in response thereto. At least one pair of linear range arrays (40, 42), each comprising a plurality of photosensitive elements, is mounted on the substrate on either side of the two-dimensional sensor array, such that the linear range arrays are separated by a baseline distance extending across the two-dimensional photometric sensor array. A lens system (20) is provided for focusing an image of a scene to be photographed upon each of the two-dimensional photometric sensor array and the linear photosensitive element range arrays. The photosensitive elements of the pair of linear photosensitive element arrays each receive light from a fractional portion of the image focused thereon and develop second light intensity related signals in response thereto. The segments of the sensor array preferably include a central segment (32), a first plurality of inner segments (34) and a second plurality of outer segments (36), wherein each segment is closely spaced and electrically insulated from adjacent segments. The photosensitive array and lens system is preferably employed in a camera having an autofocus control system for controlling the focus of a camera imaging lens based on the second light intensity related signals and an autoexposure control system for controlling the exposure of an image of the scene based on the first light intensity related signals.
